Skyrim. Always Skyrim

It’s old but gold, works flawlessly even with mods, and it feels like the Deck was literally designed for it (or vice versa)

The only real downside is that the graphics are starting to show their age vs Elden Ring or Hogwarts Legacy or some other recent RPG, but on a 7” 800p screen it doesn’t really matter and it’s still a lot of fun

I play other games on my Deck but Skyrim just fits it so well that I keep coming back to it

Or a more generic answer: pretty much any RPG. Something about a handheld just works beautifully for RPGs, that’s always been the case (see: pretty much anything Nintendo has ever done) but is particularly the case for the Deck

Enough to push a handful of currently-borderline games over the 30, 40, or 60fps threshold but not world changing

My concern is that this new slightly faster deck could become the baseline for developers, with the old one being ignored

Serial numbers are unique

If the caretakers won’t deal with it, go to the police
